Be gentle to all and stern with yourself.
Do not weep do not wax indignant. Understand.
Be thine own palace, or the world's thy jail.
Who seeks shall find.
Be kind whenever possible. It is always possible.
Either you run the day or the day runs you.
By failing to prepare, you are preparing to fail.
To know oneself, one should assert oneself.
The most effective way to do it, is to do it.
Begin to be now what you will be hereafter.
I have taught history on the high school and college levels, and am or have been a lecturer at the Smithsonian, The National Institutes of Health, and numerous colleges and universities, mostly on science fiction and technology subjects.
